Blast resistance of critical buildings and bridges is an important national need. To address this need Turner Construction is developing a blast resistant concrete construction technology called DUCON. The system utilizes concrete and steel to provide a ductlie, durable and architecturally pleasing component. The research program will examine the performance of the panels for flexural and shear resistance. The test results will be used to develop and validate analytical models which will allow for effective design for civil infrastructure systems. The research is being conducted in coordination with Turner Construction an international construction company with offices in Philadelphia and Pittsburgh.
